Abstract:
An electronically commuted electric motor with a stator and a rotor is disclosed that has permanent magnets distributed a circumferential direction to determine the magnetic field of the rotor, whereby at least one sensor makes the position or speed of the rotor recordable through direct sampling of the magnetic field of the rotor. The sensor is spaced from the stator in a way that the stator field is recorded by the sensor only to a low extent or not at all, and whereby magnetic flux-guiding elements are disposed on a front side of the rotor, which move along with the rotor and guide at least a part of the magnetic field of the rotor to the sensor. The flux-guiding elements viewed in the circumferential direction of the rotor are positioned respectively between two permanent magnets of the rotor.
